Precision Granite V Blocks
Granite V-blocks—commonly referred to as marble V-blocks—are precision metrology fixtures widely employed in mechanical manufacturing and dimensional metrology. Their primary function is to provide stable, repeatable, and geometrically accurate support for cylindrical workpieces during inspection, layout marking, and datum establishment.

Precision Core: The Art of Calibrating High-Precision V-Blocks
In the world of precision measurement, stability is everything. ZHHIMG adopts high-density (3100kg/m³) natural black granite with a Mohs hardness rating of 6–7, completely eliminating the troubles of rusting and magnetization. Every pair of V-blocks undergoes rigorous matched lapping, ensuring that the parallelism between the 90° included angle and the reference surface reaches the micron-level limit. It is the most reliable reassuring choice for your laboratories and workshops.
